NITED STATES JOHN M. LAIRD. 03: HUNTINGDON. PENNSYLVANIA.

RADIATOR SHELL.

Application filed September 20, 192-2.

To all whom. it may concern:

Be it known that I, JOHN M. Lamp. a citizen of the United States,residing at Huntingdon, in the county of Huntingdon and State ofPennsylvania, have invented new and useful Improvements in RadiatorShells. of which the following is a specification.

This invention relates to radiator shells for use on automobiles and hasfor its object the provision of a shell of novel construction wherebyair will be permitted to enter and impinge against the front of theupper tank of the radiator for the purpose of effecting cooling thereof.

in important object is the provision of a shell of this character whichis designed to be used in connection with already existing radiators andto replace the ordinary shell without necessitating any changes in theconstruction of the radiator to which it is applied.

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, easy to install.eflicient and durable in use and a general improvement in the art.

lVith the above and other objects and advantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings. inwhich:

Figure 1 is a front elevation of the shell,

Figure 2 is a vertical section therethrough showing it associated with aradiator and Figure 3 is a cross section on the line 33 looking up.

Referring more particularly to the drawings the letter A designates,conventionally, an ordinary radiator with which my device may beassociated. In carrying out my invention I provide a shell 10 which isconstructed of sheet metal in the usual manner and which is of thecustomary shape depending upon the make of auto mobile or radiator uponwhich the shell is to be used. At opposite sides the shell carries theusual lateral extensions 11 by means of which it may be mounted uponSerial No. 589,417.

the frame of the vehicle, these extensions being provided with holes 12for the pas sage of the studs provided for holding the radiator andshell therefor. The upper portion of the shell is formed as a plate 13and instead of being solid as is the usual construction this plate iscut and stamped to provide a plurality of louvers 14, that is openingsor slits having the metal outstruck to overhang them. The lower edge ofthis plate 13 is extended rearwardly and is formed with a plurality ofopenings 15 which communicate with the space between the plate 13 of theshell and the front wall of the upper tank of the radiator.

in the use of my device it will be seen that air will not only enter theopenings 15 but will also enter the louvers and thus impinge against theradiator tank and effect cooling thereof.

From the foregoing description and a study of the drawings it will beapparent that i have thus provided a simply con structed andconsequently inexpensive radiator shell which may be used to replacethose of the ordinary type and which will be highly advantageous ininsuring proper cooling of the upper tank of a radiator, it being wellknown that this upper tank is naturally the hottest point in the entirewater system of an automobile engine.

While I have shown and described the preferred embodiment of theinvention it is of course to be understood that I reserve the right tomake such changes in the form, construction and arrangement of parts aswill not departfrom the spirit of the invention or the scope of thesubjoined claim.

Having thus described my invention I claim:

A. radiator shell having its upper portion of a. plate like nature andprovided with louvers permitting ingress of air to the front wall of theradiator tank, the lower edge of said plate being extended rearwardlyand formed with a series of openings establishing communication betweenthe atmosphere and the space between the front plate of the shell andthe upper tank of the radiator to which it is applied.
